Required machining and fitting. - HIPERFIRE Hipertouch Auto Trigger

This trigger performs great but I had to take material out of the underside of the hammer for it to operate with the cam springs installed. I also had to mill material out of the receiver for the trigger to fit due to the design of the trigger. With the red springs it operated fine but I had my sights set on the lightest pull I could get and the green springs locked it up so bad I had to take out the trigger pins and wrestle the spring retainer loose from the hooks. By the time I milled the lower out, ground, and polished the trigger- Dang. This trigger is wild smooth and soft. Maybe a hair of creep and the hammer falls hard every time. I plan on using this lower across multiple calibers and that may mean using shitty steel case surplus ammo and I know I'll never have to worry about ignition with this trigger. Overall. Very happy.
